Battery (in Ruins)

On the W side of Lamb Island and just N of the ford which was replaced by a bridge in 1757. It is also c. 130m NE of the Napoleonic-era battery (RO56-016----) which formed the later, unrelated, defences. This is a rectangular grass-covered area with some bushes (dims 23m E-W; 20.5m N-S) defined by fosses at N (Wth of top 5.8m; Wth of base 2.5m; int. D 0.8m; ext. D 1.2m) and S (Wth of top 5.8m; Wth of base 2.5m; int. D 1m; ext. D 0.6m), and by earthen banks at E (Wth 2.6m; H 0.4m) and W (Wth 7m; int. H 1m; ext. H 1.6m). In plan the fosses are indented at the centre so that there are small corner bastions, and there is a raised platform (Wth 6.5m; H 0.7m) inside the bank at W, which has two double-splayed openings (min. Wth 1.2-1.5m) through the W bank for artillery. Compiled by: Michael Moore Date of upload: 24 August 2010
